centos7 sshd 접속안될때 ssh서버 ssh server

Recently, I installed sshd on centos7.

But somehow, sshd is working okay but sometimes cannot connect ssh server.

Company use static IP address for this centos server.

As I spent 3 days for trying every methods, I finally get REAL cause why this happens.

It was IP address conflict.

As IP address conflict happens, centos7 is not connected to internet.

Anyway, I assign static different IP address, it works like a charm.

If you got an error to connect ssh server, make sure server IP address is conflicted or not.

Have a nice server administrations!!!

최근에 CENTOS7 서버에 SSH서버(SSHD)를 설치했는데, 어느날은 접속이 되고, 어느날은 접속이 안되는 현상 발견.

3일간의 헛짓 이후 알아낸건 IP주소 충돌이었다.

알고보니, CENTOS7이 IP충돌이 발생하는데, 인터넷이 연결안되는거 외에는 현상이 없음.

결국은 새로운 IP설정하는 잘 되더라구요.

그럼 서버관리들 잘하시길..
